(2) Status of ZNS SSD support in F2FS, btrfs (maybe, bcachefs and other file systems) (3) Any news from ZoneFS (+ ZenFS maybe)? (4) New ZNS standard features that we need to support on block layer + FS levels? (5) ZNS drive emulation + additional testing features? (6) ZNS + computational drive? What new features would we like to see from ZNS SSD? (7) ZNS + CXL: does it make sense? Thanks, Slava
